Application filed March 12, 1908. Serial No. 420,726.

T all whom it may concern:

Be it known that I, NATHANIEL B. STONE, a citizen of the United States,residing at Outlook, 11 the county of Yakima and State of \Vashington,have invented a new and useful Turpentine-ITack, of which the followingis a specification.

This invention relates more particularly to that type of implementemployed in scoring trees for securing the sap and gum therefrom.

One of the primary objects of the present invention is to provide animplement in which the depth of the score or out can be accuratelygaged, said implement furthermore being so constructed that there issuiiicicnt clearance for the free passage of the chips and crumbs ofloose bark therethrough, thereby avoiding all liability of the samebecoming choked and inoperative.

A further object is to provide a structure that will permit the hand ofthe operator to be placed in the same position with respect to thecutting blade that it is now placed with the ordinary tool, thuspermitting the same character of working stroke.

Still another object is to provide a tool from which the blade can bereadily removed for the purpose of sharpening or in order that it may besup alanted by a new one.

The preferred form of construction is illustrated in the accompanyingdrawings, wherein Figure 1 is a perspective View of the hack.

- Fig. 2 is a sectional view through the head of the same. Fig. 3 is adetail sectional view on the line 33 of Fig. 2. Fig. e is a sectionalview on the line a 4 of Fig. 2. Fig. 5 is a rear elevation of the head.Fig. is a detail perspective view of the cutting blade. Fig. 7 is an endview of the same. Fig. 8 is a detail perspective view of the head withthe associated parts detached. Figs. 9, 10 and 11 are perspective viewsrespectively of one of the cover leaves, the cap spring and the jawplate. Fig. 12 is a detail sectional view on the line 1212 of Fig. Fig.13 is a detail perspective view of the slide block.

Similar reference numerals designate corresponding parts in all thefigures of the drawings.

In the embodiment illustrated, a handle 13 is employed, comprising acenter plate 141, to the opposite sides of which are fastened woodengrip sections 15/ One end of the plate 1% carries a suitable weight 16,while the other end is provided with a transverse head 17 disposedsubstantially at right angles to the handle and having outstandingflanges 18 along its outer margins, said flanges projecting fromopposite sides and forming in efiect a jaw. The flanges furthermore haveribs 19 on their inner faces, said ribs producing seats 20. A clampingplate or jaw 21 is associated with the inner side of the projectingportion of the head 17, and its opposite side margins project beyond theopposite sides of said head. These margins are also provided withsuitable ribs 22 in opposing relation to the ribs 19. The plate has astem 23 that extends into an opening 24 formed in the head, and aclamping nut 25, located on the opposite side of said head, is providedwith a boss 26 journaled in the opening and having a threaded socketthat receives the stem. It will thus be evident that by rotating the nutin one direction, the clamping plate will be carried toward the head.The said head furthermore has an elongated socket 27 disposedtransversely of the handle, and located therein, is a reciprocatoryslide block 28 having serrated ends. An adjusting screw 29 having aprojecting head 30 is journaled in a retaining block 31, screwed intothe head 17, and the screw 29 has a threaded engagement with the block28. A substantially U-shaped cutting blade 32 is employed that isprovided with terminal shanks 83, said shanks bearing against oppositesides of the head 17 and extending between the flanges 18 and the jawplate. The said shanks are of sufficient width so that when the jawplate is drawn toward the head, said shanks will be clamped between theflanges of the head and the flanges oi the plate. The free ends of theshanks have slots 3st, and said ends overlie the slide block 28. Coverleaves or plates 39 are arranged over said ends of the shanks, andscrews 40, passing through the cover leaves, pass through the slots 3 1and are threaded into the opposite sides of the block. The rear ends ofthe leaves 39 are doubled and bent outwardly, as illustrated at 1-1, anda cap 42, held in place by the block 31, is provided with springterminals 43 that bear against said outturned ends 31. lVith thisarrangement therefore, it will be evident that if the screws l0 areloosened, the leaves will be swung outwardly, thus producing an openthroat into and out of which the shanks 33 of the cutting blade 32 canbe readily slipped when the clamping jaws are loosened.

It will be noted that the body of the blade, designated't4, projects inadvance of the shanks 33, and terminates in a U-shaped cutting edge 45.Moreover it will be ob served that the opposite sides of the body and ofthe shanks flare rearwardly and outwardly so that the area at the rearend of the blade is considerably greater than that at the cutting edge.Projecting from the free end of the head 17 at one side of the handle,longitudinally of said handle and in spaced relation thereto, is a stemt6, the free end of the stem being at a slightly greater distance fromthe handle than the secured end. This stem, as will be clear,particularly by reference to Fig. 2, extends from a point within thecutting blade 32 to a point considerably in advance of the cutting edge,and its rear portion is preferably cut away, as shown at at in order toleave the space within the blade and particularly within the rearportion thereof completely unobstructed. For this same purpose, theouter or free end of the head is preferably cut out, as illustrated at-48. Slidably mounted on the stem 46, is a gage L9 that is disposed inadvance of the cutting edge of the blade and has a boxing 50 thatreceives said stem. An adjusting screw 51, journaled in the boxing, hasa threaded engagement, as shown at 52 with the stem. Consequently byturning the screw 51, it will be evident that the gage can be adjustedtoward and from the cutting blade. The gage, as shown, tapers toward itsfront end, and is provided with a narrow shoe or flange 53, which willoperate through the gummed surface without becoming choked or cloggedwith gum.

There are many advantages for the structure as disclosed. In the firstplace, it will be noted that one hand of the operator can be placed onthe handle in line with the cutter, so that the same Working stroke canbe secured as with the ordinary hack now in common use. At the same timethe depth of the out can be accurately gaged. In this connection, theadvantages of the relative adjustment between the cutting blade and gagewill be obvious. The structure of the cutting blade and the arrangementof parts are such that there is no liability of the implement becomingchoked, inasmuch as free clearance is provided for the chips and thecrumbs of loose bark, the discharge end being of greater area than theinlet or cutting end. The securing means for the blade is veryeffective, and when said blade is clamped thereby, it is firmly fixedagainst movement on the head.

Another important feature of the invention resides in the blade. Tn thefirst place, it will be noted that the body of the blade projects beyondthe shank. This is advantageous, inasmuch as it places the cutting edgein advance of the head so that the operators hand can be placed in linetherewith, but further than this, it provides a sufficient body thatwill permit repeated sharpening of the blade, before it is worn out.Said blade furthermore may be readily detached in order that it may besharpened or in order that a new blade may be substituted for it. Itwill thus be evident that when {it blade becomes excessively worn oruseless from any cause, it can be supplanted by a new one withoutdifficulty.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape,

proportion, and minor details of construc-' tion, may be resorted towithout departing from the spirit or sacrificing any of the advantagesof the invention.
